Introducing the OMB-DAQ-2416-4AO
Overview: OMB-DAQ-2416-4AO features
The OMB-DAQ-2416-4AO is supported under popular Microsoft
®
Windows
®
operating systems. The OMB-
DAQ-2416-4AO is a multifunction measurement and control board designed for the USB bus.
The OMB-DAQ-2416-4AO is a full-speed, multiplexed 24-bit measurement system that provides up to 16
differential and up to 32 single-ended (SE) analog inputs. It offers software-selectable analog input ranges of
±20 V, ±10 V, ±5 V, ±2.5 V, ±1.25 V, ±0.625 V, ±0.312 V, ±0.156 V, and ±0.078 V.
It also protects your computer by providing a minimum of 500 VDC input isolation between field wiring and
the USB interface.
You can configure up to 16 of the analog inputs as differential thermocouple (TC) inputs. In thermocouple
mode, the OMB-DAQ-2416-4AO includes built-in cold-junction compensation and open thermocouple
detection.
You can add up to 32 single-ended or up to 16 differential channels by connecting the OMB-DAQ-2416-4AO
to an OMB-AI-EXP32 expansion module. Each channel is software-configurable as single-ended or differential.
For each channel pair configured differentially, you lose one SE channel.
The OMB-DAQ-2416-4AO has four 16-bit analog output channels with an update rate of up to1102 S/s and an
output range of ±10 V.
The device has eight high-speed lines of digital I/O and two 32-bit counters. You can expand up to 24 DIO
channels by connecting the OMB-DAQ-2416-4AO to an OMB-AI-EXP32 expansion module.
Six banks of removable screw-terminal blocks provide connectivity to the analog input channels, digital I/O
lines, counter/timer channels, and analog outputs.
